eas sununit APPLIANCE.

T alt may concern Be it known that I, GUsTAvUs HER- "MANN, a citizen of the United States, residthe oven thereof and which may be instantly removed when desired and the stove or range used to bake by coal, .wood or 'other el. Another object resides in the provision of a gas burner which may be readily applied or positioned in an oven of an ordinary range or stove obviating the necessity of providing a specially constructed stove and without the necessity of cutting into the flues of the stove and thereby impairing the baking quality when the gas burner is removed and wood, coal or other fuel used for baking purposes.

With the above and other objects in view, the present invention consists in the combination and arrangement of parts hereinafter more fully described, illustrated in the. accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes may be made in the' form, proportion, size and minor details without departing from thespirit or sacrificingany of the advantages of the invention.

In the drawin s: Figure 1 is a horizontal sectional view t rough a stove illustrating the present invention. Fig. 2 is avertical sectional view, and Fi 3 is a detail view of the "burner including t e air flue.

Referring now more particularly .to the accompanying drawings, the reference character indicates a gas, wood,-coa'l or other stove including upper and lower air flues 6 an oven 8, and a top 9,

access beinghad to the oven 8. by way of a door'lt) at thefront, asmsual. In the oven 8'; there is illustrated the usual shelf 11 composed of wire orothersuitable material and to which a non-conducting deflecting plate 12 may-be secured-to properly distribute the 7 heat in the .QVQD .rvhbn applied through the instrumentality of my improved burner attachment.

indicates an air duct any shape in cross section, it may be round, oval or preferably rectangular, as Th s duct 13 preferably has a longitudinal opening 14 in itstop which extends throughout its length' 13 ispreferably positioned on the bottom of the oven by insertion through an opening 15 in the rear wall of the stove 5, there be mg a weighted door 16 secured to the rear wall of the stove 5 which moves normally to The character 13 which may be of that is to say, square, but is closed position to close the opening 15 when my improved burner attachment is withdrawn from the oven. The outer end. of the air duct 13 is open and when used has its outer open end preferably positioned flush with'the opening 15 or projecting slightly therefrom. The inner end of the air duct 13 is preferably closed with its rear wall provided with a substantially semicircular recess 17 -adapted to receive the inner end of the burner 18 which latter is suspended within the air duct 13 through the aforesaid longitudinal opening slightly spaced from the edges of the latter, and supported in this position by means of straps or other supporting elements 19 and 20 which may be secured in any suitable manner to the burner 18 and also to the top of the air duct 13' on opposite'sides of the opening 14, as clearly shown in the drawings. Theair duct 13 and the burner 18 are preferably disposed immediately beneath the aforesaid deflector 12 so that the heat may be properly distributed in the oven.

It is clear from the foregoing description that the air duct 13 and the burner 18 may e secured together prior to insertion in the oven and that when connected together the.

same may be readily positioned within the 13. The burner is preferably slightly spaced from the edges of the opening 14 as before stated, whereby the air is brought into direct contact with theflames from the burner.

By virtue of this arrangement it will simply the flames at require enough air to kee their oints'of highest efficiency and thereforet e airentera'ng the outer end of the duct .13 and, ass ng. up ar ly around the the spaces between the latter The air duct a tendency to cool theoven. The inner end of the burner 18 is' of course closed and the burner and air duct are so positioned that the outer end of the burner may have a close fit against the mixing device 21.

22 is an ordinary gas valve which has connection with a pipe 23 leading from the inner end disposeg cated'in said longitudinal opening and at its r on the seat of the duct withjits outer en projecting through the outer end of the duct and through the open ing adjacent the bottom of the oven, said .tube being spaced slightly from the edges of main gas supply and thisvalve. 22 may be readilyoperated in any suitable manner for the supply of gas, one means being provide the valve" with a long stem 24 which may-pass upwardly through the top 9 and be rotated in any suitable manner to operate the valve as, for instance, by means of a hand lever orthe like 24.

What I claim as new and desire to protect.

byLetters Patent is: p I

1. The combination of a cooking stove or range including an oven and provided with .an opening in oneside adjacent the upper surface of the bottom, anairduct supported directly on the bottom of the oven and having an unrestricted opening at its outer end, i

the open outer end of the duct lying within said opening in the side wall of the stove or range, the duct also having a longitudinal opening in its top which extends throughout the length thereof, and a gas tube suspended par'tly within said duct through the longitudinal opening in the top of the duct and at its outer end projecting through the unrestricted opening. at-the outer end of the duct and also projecting through the said opening in the side wall of the stove or said opening and'having openings in opposite sides slightly above the top of the air duct and ad acent the spaces between the tube and the edges of said opening in the top of the air duct.

4. A gas appliance of the character de scribed comprising an air duct provided with a longitudinal opening in its top, the duct being closed at one end and having an unrestricted opening at. its outer end, a gas tube disposed in said longitudinal opening of the duct and extending through the unrest'ricted opening of the latter, and means to secure the gas tube in the longitudinal opening of the duct, the tube being spaced slightly from the edges of .said longitudinal opening and having openings .at opposite sides slightly above the longitudinal 0 ening. in its side adjacent the bottom of the duct in spaced relation to the edges of saidlongitudinal opfiiingfand having perforations on o posite sides thereof slightly above the top 0 said duct, said gas tube extending beyond the outer end of the duct and pro- .jectingthrough said opening in the side wall of the stove or range. I

3. The combination of a cooking stove or ing of the duct whereby the air is fed rom the duct-to the flame at short range.

5. The combination of a. cooking stove or range including an oven and having an openoven, an air duct removably supported directly on the bottom of the oven and having communication: with the atmosphere only through said .0 ening in the side of the stove or range, t e bottomvof the oven being imperforate, said airduct having a longitu- ,dinal opening in its top, and a gas tube mounted in'said longitudinal opening of the duct and provided with apertures adjacent the sides of the longitudinal opening.

6. A gas appliance of the character de scribed, comprising an air duct which is substantially rectangular in cross section and which is closed at one end and which has an unrestricted opening at its other end of a width-equal to the' width of the duct, the air duct also having a longitudinal opemng formed in its upper side and which extends throughout the length thereof, a gas tube projecting'partly within and partly without the'air ductthrough the longitudinal opening and having a closed end, the gas range including an oven and an opening formed therein adjacent the bottom of the oven, an air duct removably' inserted throughsaid opening and disposed on'the bottom of the oven and having communication with the atmo'sphereithrough said opening, the duct having a longitudinal opening mits top, the inner end of the duct be1ngsemi circular. providing a seat, and agas tube 10- tube being spaced slightly from the edges of said longitudinal opening and L having slightly above the edges of said opening.

apertures therein on opposite sides thereof In testimony whereof I afi'ix my signature in presence of 'two witnesses.
